Action d'une forme réelle d'un groupe de Lie complexe sur les fonctions plurisousharmoniques
Soit un groupe de Lie complexe et une forme réelle fermée de . Un couple est dit pseudo-convexe, s’il existe sur une fonction régulière, strictement p.s.h., invariante par l’action de et d’exhaustion sur . On dit que est à spectre imaginaire pur, si pour tout de Lie, les valeurs propres de ad sont imaginaires pures. Pour à radical simplement connexe, cette dernière propriété équivaut à la pseudo-convexité de . Pour pseudo-convexe et sous une hypothèse de sous-groupe discret,...

Addendum : Finiteness theorems for discrete subgroups of bounded covolume in semi-simple groups
Addendum to "A survey of semigroups of continuous selfmaps" (with intro. by K. D. Magill).

Addendum to: On volumes of arithmetic quotients of SO (1, n)
There are errors in the proof of uniqueness of arithmetic subgroups of the smallest covolume. In this note we correct the proof, obtain certain results which were stated as a conjecture, and we give several remarks on further developments.
Addition theorems and related geometric problems of group representation theory
The Levi-Civita functional equation (g,h ∈ G), for scalar functions on a topological semigroup G, has as the solutions the functions which have finite-dimensional orbits in the right regular representation of G, that is the matrix elements of G. In considerations of some extensions of the L-C equation one encounters with other geometric problems, for example: 1) which vectors x of the space X of a representation have orbits O(x) that are “close” to a fixed finite-dimensional subspace? 2) for...
